roALL wHoM. Ir MAYv coNcEEN: l

Be it known that I, C. B. GREGORY, of Beverly, Burlington'county, New Jersey, have invented an Improvement in Stoves; and I do-hereby declare the following to be afull, clear, and exact description of the same.

My invention consists of a stove, having an air-heating space or drum, and an external pipe, with a valve,

all being arranged in the peculiar manner described hereafter, so that a greater'amountofheat in proportion to the quantity of fuel consumed maybe obtained from the stove lthan from those ofthe ordinary construction. l In order to enable others skilled in the art to make and applyy my invention, I vill new proceed to describe its construction and operation, reference being had to the accompanying drawing, 1vhch forms a part of this specification, and in whichf Figure 1 is a sectional elevation`of my improved stove, and

Figure 2 a sectional plan vie\von the line 1-2, iig. 1.

A represents lan ordinary cylindrical heating-stove, of which ais the ash-box, b the outer casing, c the fire-pot, and cZ the lire-door.-

At the rear of the stove, andcoi'nmunicating withl the interior of the same by two,l branches, e andf, is a vertical pipe, B, extending almost to the bottom ofthe stove, and open at its lowenen'd, as shown, and within th'c said pipe, between its branches e and f, is n. damper, g. i i

A casing, C, is suspended by stays z', or otherwise secured within the stove, udffcxtends from a point a little above the tire-pot c to tho topplato 7i, and the lower front portion of the said casing is bcvellcd or inclined, as shown in iig. 1, so that access' may be had to tho tire through the door d. j. A

A drum, D, ofa form correspondingxvith but smaller in size than the casing C, is. situated within the latter, and extends to the top-plate L of the stove. fi 4 I The branch e of the pipe B communicates withthe enlarged portion, j, of the chamber F,the latter boing open at the top, as shown at Z Z, iig. 1, and a short tube, en, extending from the cute' `A`asing, b, of thel stove, to the lower end of the casing D, forms a communication` with theinterior of the latter ind in the top-plate 71. of the stove, directly over this casing, is an opening, p.' v

Cold air is admitted into the pipe B at a point close to tbc door, and passes through the branch e o f the4 pipe into the 'lower portion, j, of the chamber F, which is directly over the lire.

The air thus admitted to the chamber F, being broughtl into intimate contact with the casing C, (which is exposed to thc direct action of the re,) is intensely vheated before it reaches the openings Z.

The heated air taking this course necessarily-imparts some of its heat to the drum'D, into which cold a'ir yis admitted through the tube m, and is heated before it Aescapes through the central opening in the top of the drum. f .e

The products of combustion from the fuel being dispersed laterally before escaping through the branchf to the vertical pipe, and being thus brought into' intimate contact with the outer casing of the stove, increase greatly the amount of heat radiated from the same. l

By adjusting the valve' or damper d, more or less of the air which would otherwise pass inte the 'space F, between the casings C and D, is permitted to pass directly through the vertical pipe to the chimney. Hence the quantity of heated air discharged from this space' may be regulated at pleasure. 1

I claim as my invention, and desire to secure by Letters Patenti" v 1. The combination of the outer casing A, inner-casing C, drum D, and the within-described openings for admitting cold air to and discharging it from the space between the casings C and D, end to and from the space within the drum, all as set forth.

2. The vertical pipe B, having a damper, g, situated between thc opcningc (for admitting cold air te the space between the casings'C and D) and the branch f, through which the products of combustion pass to the said vertical pipe, as specified. j@ v In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
